GLASS-FURNACE.

SPECIFICATION forming partof Letters Patent No. 319,688, dated June 9,1885.

Application filed February 13, 1885.

To all whom it may concern:

Be it known that I, DAVID FETTERS, of Baltimore city, Maryland, haveinvented certain new and useful Improvements in Glass-Furnaces, of whichthe following is a specification, reference being had to theaccompanying drawings, forming part hereof, in which Figure l is atransverse section of a glassfurnace constructed in accordance with myinvention. Fig. 2 is a vertical section from front to rear of the same;and Fig. 3 is a horizontal section thereof, the floor being shown inplan View.

Like letters of reference mark the same parts in all the figures.

My invention has for its object to improve glass-furnaces by means ofthe construction, arrangement, and combination of parts which I shallnow proceed to describe, and afterward specifically point out in theclaims.

Referring to the drawings by letter, A is the front wall, B B the sidewalls, and G the rear wall, of a glassfurnace. The front wall is open ata, to afford communication with the fire-box D, which is provided withgrate D and ash-chamber D The furnace has a vent or smoke pipe, a, andan opening, (L in the bottom. The top of the furnace is arched fromfront to rear, as at A. The sides B B are respectively at right anglesand inclined toward the front and rear, and are also inclined inwardtoward the top, as at B in Fig. 2.

E is the plateor bench supporting the four pots F F F F, which plateisdivided from front to rear, and is shaped on its outer sides tocorrespond with the sides of the furnace against which it fits.

G G are work-holes through which the glass is worked, which are locatedin upper half, B of the sides B B, the holes G G being located in theparts B of the sides, and the holes G G in the parts B.

h is the floor surrounding the furnace, and which is provided withswingways or alleys H H H H to correspond, relatively, with the pots andwork -holes. By reason of the rear sections, B, of the sides of thefurnace being inclined, or at other than a right angle, being an obtuseangle to the sections B B of the sides and the rear 0, the swing- (Nomodel.)

ways H H, in order to project at a right angle to the hole, areoutwardly inclined from instead of being parallel with the swingways HH, as seen in Fig. 3. This allows more room between the ways andfacilitates the work by allowing theblower to use a longer crane. Thearrangementof the side walls allows the rear pots to be placed nearertogether, insuring compactness and more thorough heating.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. A four-pot furnace having its sides divided near their center,forming straight sections B B, the latter of which is inclined to theformer, the upper sections of each being inwardly inclined, and thefront and rear walls being arched, as set forth.

2. A four-pot furnace having its sides divided near their center,forming straight sections B B, the latter of which is inclined to theformer, the upper sections of each being inwardly inclined, and thefront and rear walls being arched, and the furnace being provided with apot-supporting plate made in two side sections, the rear half of each ofwhich is carried nearer to the center, leaving a wider central openingin the front than in the rear, as set forth.

3. A four-pot furnace having its sides divided near their center,forming straight sections B B, the latter of which is inclined to theformer, the upper sections of each being inwardly inclined, and thefront and rear walls being arched, and the furnace being provided with apot-supporting plate made in two side DAVID FETTEBS.
